At 6:20 it should Kpc will be larger for butylamine compared to ammonia. This is because butylamine contains a hydrophobic/non polar chain, so it will be more soluble in the non polar solvent(trichloromethane). I wrote h2o by mistake. My bad.

Thank you so much sir, your explanations have been a lifesaver for me I really owe a lot to you

Sir for 2. d)(i) is it necessary to add the aq to MgCO3? or do we just have to write the state symbols

[pixiepastels]

sir you said the nonpolar solvent bracket H2O, i thought water was polar? i dont understand what they mean when they say that butylamine is more soluble in non polar solvent

Hello there! Sir can we say that (entropy change: increases) = (entropy change: positive)???
Or is it the reverse?? I'ma confused a lot, lols!

[thelabofmiracle]

hello ty for the vid, but are slashes "/" allowed in the answer ?

[rafidshafiq]

sir are the specimen papers supposed to be easier than the yearly question papers or is this the difficulty i can expect

[arnavchandak]

if butylamine donates the electron cloud to nitrogen, does that not make it more polar than ammonia, thus making it more soluble in water (and thus reducing the Kpc in the first question)?
